My husband had a medical issue right before we were supposed to board. The gate and customer service agents were very helpful, They easily rescheduled us - twice. Our luggage was waiting for us when we finally arrived in Anchorage. I'm impressed.

My husband had a medical issue right before we were supposed to board. The gate and customer service agents were very helpful, They easily rescheduled us - twice. Our luggage was waiting for us when we finally arrived in Anchorage. I'm impressed.

Boarding was fast and we didn’t sit on the tarmac very long when leaving. When flight arrived waited too long to get to gate. Aisles too narrow. Seats too small, if fat person was next to me we would have been touching that’s unacceptable.

Flight attendant in front portion of flight was surly. Aisle way too narrow, seats a bit narrow as well. If a large person had been seated next to me they would have been touching me and that’s not acceptable.

...just O.K., I paid to upgrade our seating but seemed the same old cramped seat to me! What a rip off. Movie choices were minimal, lots of stuff not worth watching!!!

I was assigned a seat other than what I chose when I booked the flight. I chose a seat somewhat behind first class so that I could get off in a timely manner to ensure a wheelchair. Instead, I was assigned the handicap seat in the back row near the gross bathroom. I noticed when I got to the airport my boarding pass did not have my seat on it. However, when I spoke to the woman at the gate about getting a wheelchair for the onboarding process, I then saw a seat number on my boarding pass. I think she gave me a seat that I didn’t choose when I booked the flight. Now I wonder if I paid more money than what the back seat was worth??

Good legroom, good food. Great landing, comfortable seat, good communication from pilot and crew. I wasn't thrilled that we were an hour late but it happens. The only two minor things was that the garbage pickup was slow and your windows need washing. Overall we will beback

The crew was pleasant! Our flight was delayed, and the pilot explained why. That was nice!

The communication was so scattered and inaccurate during the lead up to my flight and throughout the delays. We were let wondering when to arrive at the airport because the notifications said the flight 40 mins delayed and then changed back to original time! Within 1 hour of the flight! Then within minutes of the flight changed to 50 mins delayed!! Once we were boarded, it was another 3 hours till we took off!!! They’d tell us we were leaving every 30 mins but not actually leave!! It was so aggravating!!! Our flight exceeded the 3 hour delay due to airline failure and they called it a weather event! It feels like the customer has to suffer but the airline wriggles out of accountability one way or another!

Service was great on board as well as at the land crew.

The staff was friendly. The flight was fine and the food service was fine. We found the Seattle Airport to be very confusing. And not user friendly. Not enough directional signs -- it was hard to figure out where to go. As we entered the line to get to where they checked our ID before we went through the bag check, the staff member wanted us to get out of the line to walk for much longer to get to that area. It was nuts. One of our party spoke up and insisted that we stay where we were. She let us proceed.

Flight for canceled. Horrible experience.. had to rent a car to drive myself up here.

Flights were terribly delayed. I was at At,anta Airport for over 4 hours waiting for my connection.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

I know it was not in Deltas fault. But numerous delays and cancelations. I requested a hotel voucher and was told they weren't available. The lady on my hotel shuttle did receive one from American. Why the difference?

Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

Terrible flight Delayed for over an hour without a reason Told all over head storage was full. It was not. Made to check our bags. What a terrible experience. Fly American.

Older plane and it came with Fleas and flea bites!

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

See my previous comments. I was probably booked in business but was moved to economy

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

No water on the toilets, dirty sits. 4 hours delayed departure.

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

My flight was delayed for a whole day, so I lost a day of my vacation.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

It was freezing in there. When I asked about it, the response is “we would have to tell them” and then she just walked away and continued to serve beverages. Everyone was cold and they didn’t care at all.

I did not enjoy continuously being lied to about the amount of time we would circle Chicago before deciding to redirect to Milwaukee. Then the amount of time we would sit on the ground in Milwaukee waiting for gas, or to take off again. Or the amount of time it would then take to get to Chicago again, or sit on the runway waiting for a gate. The whole time continuously hopefully we would make our connecting flight that kept getting delayed as well. Only to scramble and miss it. Enough with the BS. Tell me the truth. "Sorry, things are backed up and your probably not going to make your flight. You should rebook on the next flight now rather than wait." You'll never hear those words from an airline. Speaking of which. If the flight has been redirected and/or is seriously delayed, how about making the WiFi free for everyone so they get to rebooking and reserving hotel rooms while still in the air. You've inconvenienced me already and now you want me to pay $20 for Internet so I can try to make other plans. Absolutely disgusting!

The flight was quick which gave me more time to get to my other flight.

16 Hours delayed, NOT because of the cybersecurity Microsoft issue, but because we were one flight attendant short, then when the missing flight attendant showed up two hours later, the flying shift of our pilot had expired, so, now no pilot. American Airlines is the new Spirit Airlines, actually, that is not fair for Spirit, they are probably better.

Worst flight in terms of service and food. Attendants were inexperienced, no preflight drinks, did come and give us hot towels until well into the flight. The left the Curtin open between main cabin and everyone from the main cabin went to the fist class bathroom. Food was awful! Had the golden chicken and was too lemony and inedible. No offer of coffee after. Awful!

Excellent. Attendants served preflight drinks and were courteous and nice.

It was great! It’s been awhile since I’ve flown American but this most recent experience reminded me how much I enjoy flying American. Organized. Informative. Efficient. Friendly. Can’t ask for much more, except my luggage got dinged up a bit. But that could have been the airport.

Terrible. We had about a 3 hours delay which led to us missing our connecting.
